COMBINED FOLDER ron SE ING-MACHINES.

Specification of Letters Patent. Patented .Oct. 26 1920,

Application filed March 20, 1917. ,Serial No. 156,188.

To all whom it may concern:

Be it known that I, FRED citizen of the United States, residing at Burlington, in the county of Chittenden and State of Vermont, have invented certain new and useful Improvements in Combined Folders for Sewing-Machines, of which the following is a specification.

This invention relates to an improvement ments, and then, without substituting any additional parts, an artificial seam may be produced upon the upper part of the feller proper.

The utility of a device of this character will be apparent as the description proceeds, especially when applied to the manufacture of the so-called two seam overall and pant, where an artificial seam made on the above combination feller and seamer would make a large saving in labor and material, over and above the present method of construction. g

In the accompanying drawings'forming part of the specification,

Figure 1 is a perspective view of a machine with the attachment in place, showing in dotted lines the creaser-arm in its extended position; I I

Fig. 2 is a detail perspective view of the mounting for the creaser-arm;

Fig. 3 is a vertical cross-section through the improved feller disclosing a piece of goods in the act of being creased by the creaser-arm Fig. 4 is a side elevation of the pivoted end of the creaser-arm disclosing in dotted lines the creaser-arm in its operative position;

Fig. 5 isa vertical'cross-section taken on the line 55 of Fig. 4; and

Fig. 6 is a perspective view of goods which have been folded and sewed.

To the work support 1 is afiixed the feller 2, of the usual construction as regards the lower part thereof. but which carries the H. MCCOY, a

fellin member 3 onthe upper side thereof. he feller 2 is located in the usual position in front of the two-needle sewing element 4 mounted in the frame 5. Detachably secured by a set-screw is a supporting member 7 which is slotted longitudinally as at 8. In one end of this slot is pivotally mounted the creaser-arm 9, as by the bolt 10. Pivota'lly mounted upon one end of the supporting member 1s a locklng arm 11,

provided with a cam 12 intermediate thereof. The arm 11 is bent at practically rightangles to form the handle 13. An arm 14 extends from the flanged plate 1 1 rigidly afiixed to the supporting member 7 on the opposite side of the slot 8 from the arm 11. To the arm 14: is affixed a spring 15 fastened to the arm 11 at 16. 1

The arm 9 in its inoperative position extends outwardly, as shown in dotted lines in Fig. 1. When it is desired to swing it into position, the operator gives it an inclination about its axis 10, and the bevel 17 on the inner end thereof will ride up upon the cam 12, thus moving the arm 11 about its sition incapable of movement in either "direction until the arm 11 has been raised, thus removing the cam 12 as a stop, and permitting the arm 9 to be swung to its inoperative position.

The creaser-arm 9 carries a creaser 18 adaptedto crease the goods 19 in the felling member 3, as indicated in Fig. 3.

The utility of the inventionwlll be plain when it is remembered that at present it requires two different and distinct devices to I dothe work of this combination feller and seam'er; in other words, this invention contemplates the use of onedevice to produce both real and artificial seams by the same operator and same machine, saving" time and v the other, allhfwhich takes time, and, therev fore, itis a real saving in both time and ex,

pense, which during the year is quite considerable. WVithout the combined folder, it is absolutely necessary to have two 7 separate machines to perform the same work.

For instance, in the sewing of a bifurcated piece of goods, where there has been some part out out, it will be obvious that the bifurcated portion of the goods may be joined and sewed by the lower portion of the feller, and when the end of the bifurca- .tion is reached, the work is, stopped for an instant while the goods are raised out of the lower feller with a slight twist of the operators hand, the arm 9 is swung into position, and the creaser 18 folds. the goods from the end of the genuine seam to the end of the piece of goods, the appearance of the finished article not being marred by a seam running but a part way of its length, such as results from the use of machines now on the market. If the operate 1 is making an artificial seam with the creaser arm in place on seam, as it is not necessary that the work be removed from the combined folder in passing through one feller member after passing through the other. It is obvious, however, that it might be used for the production of any kind of artificial seam.

It is believed that the operation of the invention will be apparent. lVhen the feller proper is to be used, the handle 13 is raised, and the operator is then able to swing the arm 9 about its pivot into its inoperative position, where it is out of the way, yet readily accessible; and, as soon as there is any demand for the use of the upper feller, it requires but a simple manual operation to swing the arm 9 into its operative position, where it is automatically locked and held.

The seam formedby the combined folder forms the subject matter of'a divisional ap plication filed August '30, 1920, Serial #406,748.

It is obvious that many changes might bev made in the invention, without departing from the spirit thereof, hence it is not desired to limit to the precise construction dis closed, but

I claim 1. An attachment for sewing machines comprising a feller for forming a real lap seam, a feller member connected thereto, and means cooperating with said feller member for forming an artificial lap seam,

said feller and feller member converging 'na'ting in a felling member, and means adapted to cooperate with said felling member for formingartificial lap seams.

3. The combination with a creaser arm,- of a feller having wlngsfor guiding ma- 'tGIlIl'tO be folded, one of sald wings having two guiding surfaces, one surface being capable of gulding material through the feller, and the other surface being capable of cooperating with said creaser arm for folding material for forming artificial lap seams.

' L The combination with a' feller for forming a real lap seam, a feller member connected thereto, means cooperating with said feller member i'or forming an artificial lab seam and a stitclnn unit common to both the feller and feller member, whereby both the feller and feller memberdeliver material to said unit.

5. The combination with a feller for forming a real lap seam, a feller member connected thereto, means cooperating with sald feller member for formlng an artificial lapseam, said feller and feller member converging toward a common delivery point, and a stitching unit located in the path of delivery of and common to the feller and feller member. 7

6. The combination with means for folding material to form a reallap seam, of means for folding material to form an artificial lap seam, and stitching means common to and cooperating with both of said folding means for stitching material delivered from either of said folding means.

7. The combination with a frame, of a supporting member mounted therein having a slot, an arm pivotally mounted in said slot, a stop on one side of said slot, and resilient' locking means on the other side of said slot, whereby said arm may be locked in the desired position.

8. The combination with a frame, of a supporting member mounted thereon and having a slot, a creaser arm pivotally mounted in said slot and having'a bevel portion, a locking arm pivotally mounted upon said -siipportingmember and having a cam, a flanged-plate mounted upon said supporting member, therewith, and resilient means connecting said arm with said locking'arm, the whole so arranged that the flanged-plate and the cam cooperate to firmly hold the arm in its operative position.

In-testimony' whereof I afiix my signature- FRED n, MCCOY.
